Wemos D1 Mini Soil Moisture and Temperature Sensor Box

thingiverse

A DIY project box houses a Wemos D1 Mini and soil moisture sensor. An additional hole accommodates the cable of a DS18B20 temperature probe. Power is supplied via CAT5 cable. The ESP8266 module used is the Wemos D1 Mini V3 PCB, featuring an exposed ESP8266 chip rather than one enclosed in a can on the PCB. The Capacitive Soil Moisture Sensor is sourced from banggood.com, with its product page available at https://www.banggood.com/Capacitive-Soil-Moisture-Sensor-Not-Easy-To-Corrode-Wide-Voltage-Monitor-Module-p-1309033.html. The DS18B20 temperature probe can be found on the same website at https://www.banggood.com/DS18B20-Waterproof-Digital-Temperature-Temp-Sensor-Probe-1M-2M-3M-5M-10M-15M-p-1211828.html. Wemos D1 Mini V3.0 boards, used in this project, are available from banggood.com at https://www.banggood.com/Geekcreit-D1-Mini-V3_0_0-WIFI-Internet-Of-Things-Development-Board-Based-ESP8266-4MB-p-1264245.html. This setup is running Tasmota, which forwards the data to an MQTT server and subsequently to Home Assistant. A FreeCAD model of this project is included for reference.
